The latest flat-rolled steels from AK Steel have it in for bacteria and mold spores. Thanks to an ionic-silver and ceramic coating from AgION Technologies (Wakefield, MA), the steels meet the Environmental Protection Agency standards for an antimicrobial agent, according to AK applications engineer Eric Welte. AK can apply the AgION material to both carbon and stainless steels, using either a liquid or a powder coating process. The thickness of the coating varies from 0.2 to 2 mils, depending on abrasion requirements. "You can still see the polish of stainless steel through the thinnest of the coatings," Welte notes. The new steels target HVAC, appliance, food equipment, and medical applications. AK is even building a concept house from the material to show how it keeps mold at bay. What's more, Electrolux's Fridgidaire brand will use the antimicrobial steels in a new line of stainless steel consumer appliances. AK Steel : Enter 515
Stainless beefs up solenoids
The latest stainless steel alloy from Carpenter Technology goes into corrosive operating environments that can spell trouble for solenoids. Carpenter Chrome Core 29 Solenoid Quality Stainless stacks up favorably against Type 430FR stainless. The two materials have similar magnetic properties—including high resistivity—but Chrome Core 29 outshines Type 430FR when it comes to corrosion resistance. In corrosion tests (ASTM G150), Chrome Core 29 exhibited a critical pitting temperature of 14.8C, compared to 5C for Type 430FR. As for magnetic properties, the new alloy offers a saturation flux density of 13.2 kG, coercive field strength of 1.26 Oe, residual induction of 5.20 kG, and a maximum permeability of 1,624. In its annealed condition, Chrome Core 29 has a tensile strength of 586 MPa, a yield strength of 379 MPa, and a Rockwell B hardness of 85. Carpenter Technology Corp. : Enter 516
Say good-bye to beryllium in mold making
For mold-making applications that can benefit from the cooling power of copper, but can do without beryllium, Ampco Metal Inc. has developed a new copper alloy. Called MoldMATE 90, the material features a high thermal conductivity of 90 Btu/ft/hr/°F, better than the 60 Btu/ft/hr/°F offered by a beryllium copper grade (2% Be) commonly used in mold making. At the same time, MoldMATE 90 has enough nickel in it to meet the hardness and mechanical properties that tooling components require. Ampco Metal Inc. : Enter 517
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
